The electric driving arrangement includes a driving unit and a plurality of driving rotors adapted to be driven by the driving unit to rotate. At least two corresponding driving rotors are frictionally and alignedly engaged with the guiding rib to block the sideward movement of the food marinating container at an opposed second sideward direction such that when the food marinating container is driven to rotate via the driving rotors, the food marinating container is securely retained on the supporting base.

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a marinating device, and moreparticularly to a marinating device which is capable of retaining aposition of a food marinating container so as to allow safe andeffective marination of food, such as meat, within the food marinatingcontainer.

2. Description of Related Arts

A conventional marinating device usually comprises a supporting basehaving a marinating platform, a food marinating container and anelectric driving arrangement mounted within the supporting base fordriving the food marinating container to rotate on the marinatingplatform for mixing food with a predetermined of ingredients within thefood marinating container.

U.S. Pat. No. 7,047,874 to Eastman, III, generally discloses a marinatetumbler comprising a base unit and a canister. The canister is rotatablyplaced on the base unit marination of food within the canister. In thatdisclosure, there is essentially no mechanism for retaining the positionof the canister while the canister is rotating. Thus, when the canisteris rotating, it may displace from its normal position and thiseffectively affect the marination performance of that invention.

U.S. Pat. No. 7,047,875 to Eastman, III, generally discloses amarinating food tumbler apparatus, in which the food treatment apparatuscomprises a base unit and a canister which comprises a shoulder portion,a first groove, a middle portion, and a second groove. The middleportion has a diameter larger than a diameter of the first groove andthe second groove, in such a manner that when the canister is placedonto the base unit for being rotated at a predetermined speed, theshoulder, the middle portion, the first and the second groove cooperateto ensure a proper alignment of the canister with respect to the baseunit.

Moreover, Eastman, III, also discloses a connecting hose mounted to thebase unit for selectively connecting a vacuum pump with the canister soas to allow a user to vacuum the canister for effectively marinating themeat within the canister when the canister is driven to rotate on thebase unit.

There are several disadvantages in relation to this food treatmentapparatus. First, it is said that the shoulder, the middle portion, thefirst and the second groove cooperate to ensure a proper alignment ofthe canister with respect to the base unit. This is fairly useful inretaining the position of the canister on the base unit. However, thisprior food treatment apparatus has not considered the situation wherethe user himself misplaces the canister on the base unit. Morespecifically, although the food treatment apparatus as disclosed byEastman, III, generally accomplishes a canister retention mechanism, itis by no means guarantee that the canister will be placed properly everytime the user wishes to marinate his or her food. Thus, there is nomechanism to prevent the user of the food treatment apparatus frommisplacing the canister in the first place. When the canister is indeedmisplaced, the shoulder, the middle portion, the first and the secondgroove can no longer ensure a proper alignment of the canister withrespect to the base unit, and the user has no way of detecting thesituation unless the canister derails substantially.

Second, the connecting hose of the food treatment apparatus issuspendedly extended from the base unit and selectively used foreffectively marinating the food within the canister. The problem is thatwhen the connecting hose is exposed out of the base unit, it would bevery easy to be damaged by something else. This is especially so whenthe food treatment apparatus is expected to be placed in a typicalkitchen environment. When the connecting host is somehow damaged, thiswill substantially affect the vacuuming efficiency of the vacuum pumpand therefore affect the quality of which the food is marinated.

The electric driving arrangement 30 comprises a driving unit 31 receivedin the supporting base 10, and a plurality of driving rotors 32. Theplurality of driving rotors 32 are driven by the driving unit 31 torotate, wherein each of the driving rotors 32 has a driving portion 321upwardly protruded from the utility platform 11 to contact with thecircumferential wall 21 of the food marinating container 20 so as tospacedly support the circumferential wall 21 of the food marinatingcontainer 20 in a suspended manner with respect to the utility platform11, wherein at least two corresponding driving rotors 32 arefrictionally and alignedly engaged with the guiding rib 24 to block thesideward movement of the food marinating container 20 at an opposedsecond sideward direction such that when the food marinating container20 is driven to rotate via the driving rotors 32, the food marinatingcontainer 20 is securely retained in the operation cavity 12 at aposition that the food marinating container 20 is blocked between theblocking sidewall 13 and the guiding rib 24 so as to prevent a lateralmovement of the food marinating container 20 with respect to thesupporting base 10.

According to the preferred embodiment of the present invention, thesupporting base 10 further has a top surface 17, a front side panel 14,a rear side panel 15, and two side panels 16, wherein the operationcavity 12 is indently formed on the top surface 17 of the supportingbase 10 to define the curved utility platform 11 and the blockingsidewall 13 as an inner sidewall of the operation cavity 12. The foodmarinating container 20 is arranged to be rotatably supported on thecurved utility platform 11 for marinating the food within the foodmarinating container 20.

The food marinating container 20 is preferably made of light but durablematerials so that it can be easily rotated on the curved utilityplatform. Thus, the circumferential wall 21 is preferably made oftransparent plastic materials wherein the food marinating chamber 23 isvisually accessible from an exterior of the food marinating container20. The food marinating container 20 further has an access opening 25formed at another side thereof (i.e. opposed to the container sidewall22) for communicating the food marinating chamber 23 with an exterior ofthe food marinating container 20. Referring to FIG. 1 to FIG. 3 of thedrawings, the guiding rib 24 is encirclingly formed on an inner sideportion of the food marinating container 20 for frictionally engagingwith the driving rotors 32 of the electric driving arrangement 30.

According to the preferred embodiment of the present invention, the foodmarinating container 20 further comprises a retaining rib 26encirclingly formed on an outer side portion of the food marinatingcontainer 20 for frictionally engaging with two of the driving rotors 32of the electric driving arrangement 30. More specifically, the retainingrib 26 has a retaining track 261 formed therealong in such a manner thatwhen the food marinating container 20 is disposed on the curved utilityplatform 11, the retaining track 261 is adapted to engage with thedriving portions 321 of the corresponding driving rotors 32 so as toblock an outward sideward movement of the food marinating container 20.With the help of the guiding rib 24 and the retaining rib 26, the foodmarinating container 20 can be substantially retained on the curvedutility platform 11 when the food marinating container 20 is rotatingfor marinating the food within the food marinating chamber 23.

On the other hand, the driving unit 31 of the electric drivingarrangement 30 comprises an electric motor disposed in the supportingbase 10 and operatively connected with the driving rotors 32 for drivingthe driving rotors 32 to rotate on the curved utility platform 10.Moreover, the electric driving arrangement 30 further comprises arotation control unit 34 connected with the driving unit 31 fortransforming a rotation speed of the driving unit 31 into apredetermined rotational speed of the driving rotors, and a plurality ofrotating shafts 33 in which at least one of them connects the drivingunit 31 with the corresponding driving rotors 32 in such a manner thatthe driving rotors 32 are driven to rotate at the predetermined speeddetermined by the rotation control unit 34. As such, the manufacturer ofthe marinating device is able to decide an optimal rotational speed ofthe driving rotors 32 (by pre-programming the rotation control unit 34)in order to accomplish a desirable rotational speed of the foodmarinating container 20. The rotation control unit 34 comprises a speedcontrol circuitry 341 electrically connected with the driving unit 31which then adapted to drive the corresponding rotation shaft 33 torotate in accordance with a pre-set speed determined by the speedcontrol circuitry 341.

The marinating device further comprises a vacuum device 40 provided onthe supporting base 10 for vacuuming the food marinating chamber 23 ofthe food marinating container 20 before it starts rotating to marinatethe food within the food marinating chamber 23. The vacuum device 40comprises a vacuum unit 41 received in the supporting base 10, a vacuumhead 42 adapted for communicating with the food marinating chamber 23,and a vacuuming tube 43 connected between the vacuum unit 41 and thevacuum head 42, in such a manner that when the vacuum unit 41 isactivated, air within the food marinating chamber 23 is sucked out of itvia the vacuum head 42 and the vacuuming tube 43 so as to create avacuum environment with in the food marinating chamber 23. It isexpected that when the food marinating chamber 23 is completely orsubstantially vacuumed, marinating of food within the food marinatingchamber 23 will be made the most efficient and effective.

Accordingly, the food marinating container 20 further comprises asealing lid 27 detachably provided at the access opening 25 thereof forselectively blocking access to the food marinating chamber 23 and forsealing the food marinating chamber 23 so as to ensure an optimal vacuumenvironment therewithin.

It is worth mentioning that the supporting base 10 further has areceiving compartment 18 indently formed on the curved utility platform11 for normally receiving the vacuum device 40, and a compartment cover181 operatively connected with the curved utility platform 11 forselectively covering the receiving compartment 18. As such, when thevacuum device 40 is not in use, the vacuum head 42 and the vacuumingtube 43 are normally received into the receiving compartment 18, and thecompartment cover 181 is closed for protecting the vacuum device 40.When the vacuum device 40 is to be used for vacuuming the foodmarinating chamber 23, the compartment cover 181 is opened to allow thevacuum head 42 and the vacuuming tube 43 to extend towards the sealinglid 27 of the food marinating container 20 for vacuuming of the foodmarinating chamber 23. Thus, the sealing lid 27 further comprises vacuumaccess valve 271 provided in the sealing lid 27 for operating between asealing mode and vacuum mode, wherein in the sealing mode, the vacuumaccess valve 271 is closed for blocking fluid communication between thefood marinating chamber 23 and an exterior of the food marinatingcontainer 20, wherein in the vacuum mode, the vacuum access valve 271 isopened for allowing the vacuum head 42 to be inserted into the foodmarinating chamber 23 so as then to allow vacuuming of the foodmarinating chamber 23 via the vacuum head 42 and the vacuuming tube 43when the vacuum unit 41 is activated.

More specifically, referring to FIG. 4A to FIG. 4C of the drawings, thesealing lid 27 further has a vacuum opening 272 communicating the foodmarinating chamber 23 with an exterior thereof, while the vacuum accessvalve 271 comprises a valve housing 2711 having an air outlet 2712adapted for engaging with the vacuum head 42 of the vacuum device 40,and an air passage 2713 communicating the food marinating chamber 23with an exterior thereof, wherein the vacuum access valve 271 is mountedon the sealing lid 27 at the vacuum opening 272 for allowing passage ofair between the food marinating chamber 23 with an exterior of the foodmarinating container 20 via the air passage 2713 and the air outlet2712.

The vacuum access valve 271 further comprises a valve actuator 2714,having two air blocking members 2716, operatively mounted on the valvehousing 2711, and a valve member 2715 movably provided within the valvehousing 2711 to communicate with the valve actuator 2714 in such amanner that the valve member 2715 forms a boundary of the air passage2713. When the vacuum access valve 271 is in the sealing mode (FIG. 4A),the valve actuator 2714 is rotated to drive the air blocking members2716 to close the air passage 2713 of the valve housing 2711 so as toblock air exchange between the food marinating chamber 23 and anexterior thereof via the vacuum access valve 271, and when the vacuumaccess valve 271 is in the vacuuming mode (FIG. 4B), the valve actuator2714 is rotated to drive the air blocking members 2716 out of the airpassage 2713 so as to allow air exchange between the food marinatingchamber 23 with an exterior thereof via the air passage 2713.

It is also worth mentioning that when the vacuuming and marinationprocess have all been completed, the user must release the vacuum accessvalve 271 before he or she can take out the marinated food from the foodmarinating chamber 23. As a result, the user must turn the valveactuator 2714 which then drives one of the blocking member 2716 out ofthe air passage 2713, while the other blocking member 2716 is rotated topartially block the air passage 2713 and to slightly push the valvemember 2715 tilting at a predetermined angle for allowing atmosphericair to pass through the unblocked portion of the air passage 2713 andreach the food marinating chamber 23. Once air has reached the foodmarinating chamber 23, pressure within and out of the food marinatingcontainer 20 becomes equilibrium (FIG. 4C).

In order to allow simultaneous marination and vacuuming of another foodmarinating container 20, the supporting base 10 further has a receivingchannel 182 indently formed on the curved utility platform 11, andextended from the receiving compartment 18 to a side edge of thesupporting base 10, wherein the vacuuming tube 43 of the vacuum device40 is allowed to selectively extend out of the receiving compartment 18via the receiving channel 182. As a result, when the electric drivingarrangement 30 is operating to rotate the food marinating container 20,the vacuum device 40 can also operate at the same time to vacuum anotherfood marinating container 20. This feature is important in that a userof the present invention can speed up the whole marination process whenhe or she needs to marinate meat of different kinds which are separatelycontained in different food marinating container 20.

Referring to FIG. 5 of the drawings, the food marinating container 20further comprises a plurality of marinating blades 28 spacedly providedin the food marinating chamber 23 at an inner side of thecircumferential wall 21 for facilitating marination of the food insidethe food marinating chamber 23. More specifically, each of themarinating blades 28 has a different predetermined length and isprotruded from the inner side of the circumferential wall 21 at apredetermined angle to form an inclined marinating blade portion 281 andtwo rounded root portions 282 at two sides of the respective marinatingblade 28, in such a manner that when the food marinating container 20 isdriven to rotate on the curved utility platform, the food can beuniformly and effectively marinated by the marinating blades 28. It isworth mentioning that since each of the marinating blades 28 has tworounded root portions 282, the possibility of uneven marination would beminimized. Moreover, food residuals accidentally stuck at the roundedroot portions 282 are easier to clean.

According to the preferred embodiment of the present invention, thereare altogether four driving rotors 32 provided on the curved utilityplatform 11 for rotating the food marinating container 20, wherein thefirst and the second driving rotors 32 are opposedly provided at aninner portion of the curved utility platform 11, while the third and thefourth driving rotors 32 are opposedly provided in the outer portion ofthe curved utility platform 11. It is important to point out, however,that the first and the second driving rotors 32 are mounted at analtitude (FIG. 3) which is slightly higher than that of the third andthe fourth driving rotors 32 such that when the food marinatingcontainer 20 is placed on the curved utility platform 11, the foodmarinating container 20 is slightly tilted, as a result of gravity,towards the blocking sidewall 13 of the supporting base 10 so as toensure that the food marinating container 20 is automatically retainedon the curved utility platform 11 of the supporting base 10.

Furthermore, the vacuum device 40 further comprises a vacuum controller44 provided at the supporting base 10 and electrically connected withthe vacuum unit 41 for adjustably controlling the vacuum parameters ofthe vacuum unit 41. The vacuum controller 44 comprises a vacuum operator441 provided at the supporting base 10 for allowing a user to adjust thevacuum parameter of the vacuum unit 41. Moreover, the vacuum controller44 further comprises a vacuum sensor 442 provided at a bottom side ofthe supporting base 10 to electrically connect with the vacuum unit 41,in such a manner that the vacuum sensor 442 is adapted to detect avacuum condition within the food marinating chamber 23 and deactivatethe vacuum unit 41 when the food marinating chamber 23 has beencompletely vacuumed. More specifically, the user may adjust the time ofvacuuming so as to achieve an optimal vacuum performance for marinatingthe food within the food marinating chamber 23. Alternatively, othervacuum parameters (e.g. strength of vacuuming) may be adjusted toprovide different vacuuming function for the user of the presentinvention.

Finally, the electric driving arrangement 30 further comprises a controlpanel 35 provided at a front side of the supporting base 10 andelectrically connected with the driving unit 31 and the vacuum device 40for allowing a user to control an operation thereof through the controlpanel 35. Thus, the control panel 35 may comprise an on/off button, atime control button, and a status indicator for indicating theoperational status of the vacuum device 40 and the electric drivingarrangement 30.

The operation of the present invention is as follows: the user has firstto put a predetermined amount of meat and other ingredients into thefood marinating chamber 23. The user has then to close the foodmarinating chamber 23 by the sealing lid 27 and turn the sealing lidinto the vacuum mode. After that, the user has to pull out the vacuumhead 42 and the vacuum tube 43 for vacuuming the food marinating chamber23. He or she may do so by inserting the vacuum head 42 into vacuumaccess valve 271. After vacuuming, the user is in the position ofturning on the electric driving arrangement 30 and start the marinatingprocess. After marination, the user should release the vacuum accessvalve 271, remove the sealing lid 27, and take out the marinated foodaccordingly.

One skilled in the art will understand that the embodiment of thepresent invention as shown in the drawings and described above isexemplary only and not intended to be limiting.
